inline

Evaluate 2D spline function (described by its spline coefficients) at a given coordinate.

The spline coefficients represent a 2D spline function defined on a B-splines (basis splines). They can be obtained via various methods, such as using a SplineBuilder2D.

Remark: calling SplineBuilder2D then SplineEvaluator2D corresponds to a 2D spline interpolation.

Parameters

coord_eval	The coordinate where the spline is evaluated. Note that only the components along the dimensions of interest are used.
spline_coef	A ChunkSpan storing the 2D spline coefficients.

Returns

The value of the spline function at the desired coordinate.

inline

Evaluate 2D spline function (described by its spline coefficients) on a mesh.

The spline coefficients represent a 2D spline function defined on a cartesian product of batch_domain and B-splines (basis splines). They can be obtained via various methods, such as using a SplineBuilder2D.

This is not a nD evaluation. This is a batched 2D evaluation. This means that for each slice of coordinates identified by a batch_domain_type::discrete_element_type, the evaluation is performed with the 2D set of spline coefficients identified by the same batch_domain_type::discrete_element_type.

Remark: calling SplineBuilder2D then SplineEvaluator2D corresponds to a 2D spline interpolation.

Parameters

[out]	spline_eval	The values of the 2D spline function at the desired coordinates. For practical reasons those are stored in a ChunkSpan defined on a batched_evaluation_domain_type.
[in]	coords_eval	The coordinates where the spline is evaluated. Those are stored in a ChunkSpan defined on a batched_evaluation_domain_type. Note that the coordinates of the points represented by this domain are unused and irrelevant (but the points themselves (DiscreteElement) are used to select the set of 2D spline coefficients retained to perform the evaluation).
